1 | BMS | | Global 90-South LI-200 | 05/12/2021 | 12:12:00 | 05/12/2021 | 12:54:00 | The relay multiplexer on the SRRL BMS radiometer tower had a problem (old age/possible moisture) and was replaced during this time, the (4) vertical LI-200s will read bogus. |
2 | BMS | | Global 90-South LI-200 | 09/25/2020 | 09:07:00 | 12/15/2021 | 19:31:00 | DATA CORRECTED on 12/17/2021: Irradiances were increased by 0.675% due to revised BORCAL report for all BMS shortwave radiometers calibrated in 2020 and 2021. |
3 | BMS | PY28246 | Global 90-South LI-200 | 07/31/2015 | 12:55:00 | 08/03/2015 | 13:58:00 | The LICOR was swapped out with a sensor just calibrated in BORCAL, however the signal was reading zero. The back shell was tightened and apparently the solder joints broke. Sensor was removed from service, however a short was not placed on the channel and is reading bogus (but real looking) data. Channel was shorted on 8/3/2015 at 08:01 MST. Until the sensor can be repaired the previous sensor (SN PY28249) was reinstalled on 8/3/2015 at 13:59 MST.

4 | BMS | | Global 90-South LI-200 | 06/14/2004 | 00:00:00 | 11/30/2005 | 23:59:00 | There were two guy wires on the SRRL BMS radiometer tower which would shade the Global 90-South PSP & LI-200 twice during the day for about 5 minutes (different times for each instrument). The guy wires were moved on 11/30/2005 to a location below the instruments to prevent the shading from occurring. |
